GAS-CLEANER'.

To aZZw/Lom t may concern.'

Be it known that I, ALFRED ERNST, a citizen of the United States,resident of Pit-tsburgh, in the county of Allegheny and State of'Pennsylvania, have made a certain new and, useful Invention inGas-Cleaners; and I' declare the following to be a full, clear,and'exact description of the same,- such as will enablel others skilledin the art to which it appertains to make' and use the invention,

reference being had to the accompanying drawings, and'to letters orfigures of reference marked thereon, which form a part of thisspecification.

Figure 1 is a central vertical section of the invention. Fig. 2 is asection on the line 2-2, Fig. 1.'

The object of this invention is to provide an improvement inapparatusfor cleaning gas, particularly that from bituminous coal, and itconsists in the novel construction and combinations of parts, ashereinafter set forth.

In the accompanying drawings, illustrating the invention, a casing isindicated by the numeral 2, having an inlet 3, for the gas at its lowerportion, and an outlet 4, at its upper portion.

Through the top of the casing, which isA designed to be of cylindricalcharacter, eX- tends a shaft 5, to the upper part of which is attached adriving pulley 6. .Below the pulley, the entrance of the shaft into thecasing is provided with a water seal device 7, in a central recess inAthe top, around which is a drying compartment 8, of annular form,provided with perforated racks 9, upon which drying material, such ascoke or wood shavings,is placed. This portion of the casing ispreferably of larger diameter than thebody part below, in order toprovide more room for drving material, and to cause the gas to passthrough the co1npart nient more slowly than through the body portion.The top portion of the casing may be connected to the cylindrical lwalllof the body part by an inelined'wall portion 10, the lower part ofwhich projects into the chamber ofthe body part in the form of a,

downward and inward sloping flange 11.

The casing is provided with a water h0ld` ing drip connection, tank orcistern 12, at its bottom, 'which is preferably inthe form of afwaterseal, .the lower end of the wall of the casing extending down into thesaine,

and anA Overflow pipe 13', being connected in specification of LettersPatent. Application filed December 13, 1912. Serial No. 736,556.

proper position to provide a constant water level.

lVithin'the casing the shaft 5, is provided with disks 17, and fanblades 14, in series one above another, sloping ian'ges 15 of the casingbeing'respectiv-ealy arranged between the disks and ext-ending inwardand downward from the casing wall toward the disks, the-edges ofwhichare substantially in vertical alinement with the -ed ges of the ianges.lIn the construction shown the disks 17, are

provided with fan blades 14. The lowerianges 15,' ofthe casing may havethe same as the iange 11, in the upper part. Fan blades 16, are securedto the end of th'e shaft below the series of disks 17.- In the lowerportion of the casing is lprovided a'tubular partition passage 18, thewall 19, of whichrextends upward a short distance to join a Islopingannular partition wall 20, which is attached to the inside of the casingwall. The tubular wall 19, of the passage is .I provided'with ahorizontalcircumferential series ofpassages, notches or serrations 21,at'or just above the water level, so that the casing is arranged to beseparated by the -water at the bottom thereof into an upper main chamber24and an annular compartment-'25, below, around the main chamber,and'into which the inlet at 3 provides for the entrance of the crudegas. Later dis.- charge spouts 22, directed toward the serration's 21,ma be vprovided in the Aeasing around the passage 18, and, in the upperpart of the c sing below the drier co1npartnient, one or nore jets aredesigned to be jintrotli'iced, to provide additional water for use,'invconnection with the' flanges and disks, in cleaning and coollng the gas.

Inthis apparatus it is designed to pr0- mote'rapidit-yof action throughsimple construction. 'lhe heated gas entering the annular compartment inthe lower portion of the easing passes inward through the ser'- rationsof thetubular wall 19, and throughE the wat rat the water level, in'suchwlse that it' s separated or subdivided by thev action of these"notchesand the water into small portions -in bubble form, Awhereby it 1sdesigned to be evenly distributed yin its entrance tothe main chamber.ber it is drawn upward through the passages between the cylinder angesand the disks, which are designed -to be supplied with' In thischamwater-from above. All of the crude and heated gas entering from theproducer is in this way immediately subdivided in small portions andsubjected to the cleansing and cooling action of' the body of water atthe bottom of the casing. And much of thel tarl is eliminated, and tosoine extent the ammonia and soluble by-products are taken up by thewater, after which the upward moving gas is subjected to centrifugalmovement and active washing, through the operation of the rotary disksor ledges of the shaft, cooperating with the interior inclined flangesof the casing, in connection with the films and particles of vapor orwater spray produced from the upper water supply. The inclination of thecasing flanges and of the passage wall is designed to be about 45, orsufficient to facilitate the. downward flow or drain of solutions ofextractive into thek tank. Before passing the gas out of the apparatusit is caused to pass through the drying material on the racks inthe-upper compartment of the casing, where it is designed to be relievedof moisture, so that when it is discharged from the apparatus it is incondition for immediate use.

l. Apparatus for cleaning gas, comprising a cylindriform casing havingan interiorly flanged main chamber, a drier chamber in its top,perforatedv racks between the drier chamber andy main chamber, anentrance lchamber circumscribing the main chamber, an overflow waterholding connection at the bottom of the ci sing, a tubular partitionbetween the entrance chamber and the main chamber having a horizontalseries of passages at the water level, and rotary disks and fan devicesin the main chamber.
